Although Chamber's second book is set in the same universe as her first, it is far from a sequel. She switches perspectives between an AI trying to hide her identity among organics, and a young clone-girl born to slave away in a scrapped-tech factory. She covers issues of body dysphoria and perseverance in the worst situations, as well as what it means for each of us to live our lives on our own terms. I loved it even more than her first book!
